Jill; The HTP chips are still redeemable at Trump Plaza.... and yes, I do consider them to be "obsolete" since they are not used there any more.

Let me switch gears for the purposes of discussion. How many of us has had something that we could not get a replacement part in order to fix something because the item was "obsolete"?

Whether it be an old obsolete computer; an obsolete automobile part; a obsolete tube-type radio or tv; an obsolete appliance; etc., because of obsolescence it could not be serviced.....; if one WAS able to obtain a used replacement part, and the item was put back into service.... would it no longer be obsolete?
